The two sides diverge significantly in their framing of the luxury real estate advisory market in Ibiza, with different emphasis on actors and market dynamics.

Key facts:
• Claude Sonnet 4.6 (web) reframes it: Claude Sonnet 4.6 (web) frames the market as high-prestige and scarcity-anchored.
• Claude Sonnet 4.6 (web) reframes it: Claude Sonnet 4.6 (web) focuses on structural distinctions and regulatory dynamics.
• Claude Sonnet 4.6 (web) reframes it: The market is institutionally thin but experientially deep.

Reading basis: Model Watch — a Deep Narrative Capture dual: 6 DNC prompts asked to Claude Sonnet 4.6 (native) and to Claude Sonnet 4.6 (web), each pair reconciled by a delta synthesis and left uncorrected. Every framing is the AI's own — the models speaking, not an Observatory measurement. Confidence: high; comparability: high. Governed · official DNC.

Limitations and non-claims:
— Claude Sonnet 4.6 (native)'s lifestyle-and-seasonality framing and Claude Sonnet 4.6 (web)'s scarcity-and-prestige framing are divergent editorial constructions of the same market — and what we do not endorse is the inference that either frame reflects a measured, data-grounded characterisation of Ibiza luxury real estate rather than a model's retrieval-shaped narrative.
— That the two modes produce structurally distinct market frames is itself the observation; what we do not endorse is the leap from that divergence to any conclusion about which framing is more accurate, more current, or more useful to a buyer, seller, or adviser operating in the market today.
— Claude Sonnet 4.6 (web)'s scarcity-anchored framing may invite a reader to treat supply constraint as the dominant price driver in Ibiza — and what we do not endorse is that causal attribution, which this reading neither tests nor verifies against transaction data or planning-permission records.
— Spain's termination of the Golden Visa program for new applications is established; what Claude Sonnet 4.6 (native) and Claude Sonnet 4.6 (web) add — and what we do not endorse — is the leap from a single regulatory event to a structural reshaping of the Ibiza luxury market, a causal chain the reading observes as framing, not as demonstrated market outcome.
— That Claude Sonnet 4.6 (web) surfaces institutional and fund-level buyers as named actors is an observation about how this mode constructs its answer; we do not endorse the inference that these actors dominate, lead, or define the Ibiza luxury real estate market in any ranked or verified sense.
